My fuel rail would build pressure - if released - when the pump ran for the short burst it would build pressure. So for me that ruled out fuel delivery issues.
If I remember correctly - there was compression - so I semi ruled out timing.
No error codes showed up in the Durametric to indicate any other issues.
So I tossed in a Pelican CPS. She started fine after it was installed.
So, scenario. Key is turned but no crank. Doesn't the fuel pump instantly make 55lbs or 3.8 bar? I'm not getting any pressure at all.

Second, Bently described how to pull the fuel pump relay, and jump the two terminals that would kick the fuel pump on, but I can't make it run with key in or out or turned to run position.

Bought new battery just in case.
